ERRATA: I have updated the pattern to correct an error. All Hdcssflo (Half double crochet slip stitch front loop only) should just be hdcss (Half double crochet slip stitch). I also added finished measurements for the hat when laid flat before seaming. The revised pdf is now available.

This hat is crocheted flat in rows, folded in half and seamed together, then cinched closed at the top. The beanie is one size, to fit the average woman’s head, but circumference is easily adjustable by adding or subtracting the number of rows. You will need a P (11.5mm) hook, scissors, needle to weave in ends, and one skein of Lion Brand Thick and Quick Yarn. Other size 6 super bulky yarn can be used, but I have not tested other yarns.
